I've been looking all over the place to find the solution to this but haven't had success. I have a Sketchflow project and I want to scale every Screen to the browser resolution on running, as in scaling every element of the current Layout to fit the screen.
Do you want the objects themselves to get bigger to fill the screen or to spread out? For objects to get bigger you can wrap the whole thing in a ViewBox.

Good morning!
I'm currently trying to create a view similar to this mockup.
I have put down 3 different screen sizes so you can see the issue.
I have a header background image (grey box) with an angled bottom. On the right I want to display an image, which obviously needs to be positioned.
Positioning it horizontally is no issue but how can I position the image vertically? I have it positioned fixed for one screen size but obviously need to make it flexible.
Any ideas? Help would be much appreciated!

You can definitely use measure as #rajesh pointed out, or you can use Dimensions. As far as getting the layout consistent across devices, using position absolute and measuring the device height should allow you to get consistency across these devices.
Check out this example I set up, it should be a good starting point at least.

I am having strange artifacts on a tiledmap while scrolling with the camera clamped on the player (who is a box2d-Body).
Before getting this issue i used the linear filter for the tiledmap which prevents those strange artifacts from happening but results in Texture bleeding (i loaded the tiledmap straight from a .tmx file without padding the tiles).
However now i am using the Nearest filter instead which gets rid of the bleeding but when scrolling the map (by walking the character with the cam clamped on him) it seams like a lot of pixel are flickering around. The flickering results can get better or worse depending on the cameras zoom value.
But when I use the "OrthoCamController" class from the libgdx-Utilities which allows to scroll the map by panning with the mouse/finger i don't get these artifacts at all.
I assume that the flickering might be caused by bad camera-position values received by the box2d-Body's position.
One more thing i should add here: The game instance runs in 1280*720 display mode while my gamecam renders only 800*480. Wen i change the gamecam's rendersolution to 1280*720 i don't get those artifacts but then the tiles are way too tiny.
Has anyone experienced this issue or knows how to fix that? :)
I had a similar problem with this, and found it was due to having too small a decimal value for the camera position.
I think what may be happening is some sort of rounding with certain tile columns/rows in the tilemap renderer.
I fixed this by rounding to a set accuracy, like so:
camera.position.x = Math.round(player.entity.getX() * scalePosition) / scalePosition;
Experiment with various values, but I got it working by using the tile size as the scalePosition value.
About tilesets, I posted a solution here: Getting gaps between tiled textures with libgdx
I've been using that method with Tiled itself. You will have to adjust "margin" and "spacing" when importing tilesets in Tiled to get the effect working.
It's 100% working for me :)
I am designing a simple music app where the user gets to play instruments i.e. Drums, and the problem that I am facing is with resolutions.
The drums are images, which I have converted them into buttons. Everything looks great at the state that I have designed it.
However, when I switch to other resolution states, the button(image) are distorted, e.g. skewed, scaled, and looks nasty.
I have tried designing or arranging them via selecting 'Enable state Recording', but the specific designs for that state are not being saved.
Have you tried the approaches discussed here? http://msdn.microsoft.com/en-us/library/windows/apps/hh465362.aspx For the actual button sizes, make sure you are not fixing the width/height with pixel values. Use * weighted rows and columns to layout your grids and have the buttons autosize to fill a given cell in the grid. Then match with the appropriate image resource per the article.
Grids are great for dividing up available space but they can't account for changes in aspect ratios. If your items are still set to Stretch (or Fill) then they can end up out of aspect ratio. Another option is to design the entire layout at a fixed size (let's say 1024 x 768 or 1366 x 768) and wrap the entire thing in a ViewBox. ViewBox will scale all elements equally and maintain the aspect ratio, adding letterboxing (or empty space) on the sides / top & bottom if necessary. This might be a better approach for a drum kit.
Hope that helps.
Redid the whole project of designing again.
This time, I put the image inside a specific grid and that made things lot better. :)
Background: I recently got two monitors and want a way to move the focused window to the other screen and vice versa. I've achieved this by using the Accessibility API. (Specifically, I get an AXUIElementRef that holds the AXUIElement associated with the focused window, then I set the NSAccessibilityPositionAttribute value to move the window.
I have this working almost exactly the way I want it to, except I want to animate the movement of windows. I thought that if I could get the NSWindow somehow, I could get its layer and use CoreAnimation to animate the window movement.
Unfortunately, I found out that this isn't possible. (Correct me I'm wrong though -- if there's a way to do it this way it'd be great!) So I'm asking you all for help. How should I go about animating the movement of the focused window, if I have access to the AXUIElementRef?
-R
--EDIT
I was able to get a crude animation going by creating a while loop and moving the position of the window by a small amount each time to make a successful animation. However, the results are pretty sub-par. As you can guess, it takes a lot of unnecessary processing power, and is still very choppy. There must be a better way.
The best possible way I can imagine would be to perform some hacky property comparison between the AXUIElement info values for the window and the info returned from the CGWindow api. Once you're able to ascertain what windows in the CGWindow API match AXUIElementRefs, you could grab bitmaps of the current window contents, overlay the screen with your own custom animation draw of the faux windows, then as you drop the overlay set the real AXUIElementRef's to the desired-end-animation positions.
Hacky, tho.
I've been trying to render the entire canvas in an IWebBrowser2 control to a bitmap. IViewObject::Draw seems to be the most promising approach, but I can't get it to render anything that would requires a scroll to show. While I could automate the scrolling and stitch the images together, this would look weird with any fixed position elements. Is this even doable?
Additionally, I've tried to set the controller's size to one that would allow the entire contents to display without needing to scroll, but Windows caps the max size to the current screen resolution, so that only gets me partially there.
Any help would be much appreciated. I'm currently doing this in the context of Win7 and IE8, but I don't think that should matter much.
Sorry it took so long for me to follow up with the answer to this.
I wrote up an article detailing how to trick Windows into allowing you to resize a window larger than the virtual screen resolution, allowing functions like PrintWindow or IViewObject::Draw to capture the entire client area (i.e., the browser canvas).
http://nirvdrum.com/2010/03/25/how-to-take-full-page-or-full-canvas-screenshots-in-windows.html
An actual implementation of the technique can be found in my SnapsIE repository on GitHub (username: nirvdrum). Unfortunately I don't have enough karma to post two hyperlinks. The repository is linked from the article though.
It is very likely an IE optimisation that avoid to draw more than required. You might be able to scroll the window and call IViewObject::Draw in a loop without any animation occuring ?
I'm surprised that Windows caps the max size to the current screen resolution. Are you sure about that ?
